That escalated quickly. In law there is a principle of proportionality [0]. It's the reason why jaywalking isn't punished by 60 days in prison or by getting sent back to your country and banned from ever travelling to any country that has pedestrian crossings. Also laws should apply equally to everybody. How would such a law apply to locals? Withdraw citizenship?
I think hitting them with fines or paying damages is a different matter and might just be enough. Banning someone from half a continent is certainly a knee jerk reaction.
Impossible punishments also have some side effects. Even law abiding tourists start avoiding the country completely if they know a mistake lands them on the ban list for half a continent. And perhaps worse, if one makes a mistake they no longer have anything to lose by doing it again until they leave the country, they're facing the ban anyway. See the 3-strikes law [1] where the third strike is almost always murder because by then the culprit knows they'll do life anyway. The deterrent is gone.
